Phoenix Applet & WebStart Revival

Phoenix is our plugin for Chromium-based web browsers, designed to display Java applets and WebStart applications with a focus on security, ease of use, and compatibility from Java 8 to the latest available version.

Simplifies the deployment and maintenance of applications written in Java without having to download local components from remote applications.

Compatible with Chrome, Opera, Edge, Brave, Chromium.

Step 1: Windows Installer (bat file): https://www.mc3d.cl/documents/d/guest/install_phoenix_appletviewer_windows

The installer downloads two zip files from MC3D:

  • A version of Java 21 with JavaFX support from Azul Systems.
  • The latest version of Phoenix in a zip version.
  • Phoenix will launch to demonstrate that it is active.
  • A shortcut to the installation folder will be created on your desktop for you to use in step 2.

Step 2: In your browser's Extensions module, activate the "Developer Mode" option.

 

Click on Upload unpackaged extension.

Access the Phoenix Applet & WebStart Folder on your computer's desktop.

 

Step 3: The folder you need to select is as follows:

 


 

We have validated applets from Java 1.1 to Java 25 (Beta) running on Phoenix.

Why JRE 21 and not 24?

The latest version with Long Term Support with sandbox protection for applets is 21; once we implement a higher version, we will include it by default.

If you need to change the Java version for running applets, look in your operating system for the enviromnent variable PHOENIX_JAVA_HOME

Currenttly the Plugin for web browsers in Linux and Mac is in development status.

Use Phoenix AWR in direct way downloading the next jar file:

Running a Applet from NASA on Java 24 - Chrome

What is an Applet

An applet is a small program developed in Java that runs within a controlled environment, typically embedded in web pages or run by specialized viewers. Although their use in browsers has been displaced by other technologies, applets remain relevant in corporate environments and legacy systems.

From a business perspective, an applet represents a secure, modular, and reusable way to distribute specific functionality to end users without the need to install additional software. For example:

In financial institutions, applets are used to validate digital signatures or interact with security devices.

In industrial or government infrastructures, they allow remote interfaces to be viewed, systems to be monitored, or modules that were developed decades ago but are still critical to integrate.

Key business benefits:

  • ✔️ Reduces deployment time: no local installations required.

  • ✔️ Compatible with restricted or controlled environments.

  • ✔️ Leverage previous investments in Java development.

  • ✔️ It can be integrated with modern solutions through viewers such as Phoenix Applet Viewer, allowing you to extend its useful life without compromising security or compatibility.

In short, applets offer an efficient and controlled alternative for keeping critical applications operational while still meeting the organization's strategic objectives.
